Weather in September
Temperature
Welcoming September, Whitehead notes an average high-temperature of a moderately hot 85.5°F (29.7°C), nearly consistent with August's 88.9°F (31.6°C). Throughout the month of September, Whitehead observes an average nighttime temperature of 66.9°F (19.4°C).Heat index
In September, the average heat index is appraised at a very hot 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
